Time-space-resolved diagnostic technique for Z-pinch plasma investigation

In order to further understand the Z-pinch physical process and to optimize the experimental design,it is necessary to develop time-space-resolved diagnostic technique and corresponding equipments for investigation of imploding plasma and radiation distribution.Based on these diagnostic technique and equipments,experimental studies of plasma imploding process and spatial distribution can be conducted,which provide experimental verifications of numerical simulations.A brief summary of recent researches on the time-space-resolved diagnostic technique is given,including spatially integrated time-dependent X-ray power measurement,temporally integrated X-ray pinhole photography,X-ray framing photography,time-resolved 1D imaging,and plasma shadowgraph using UV laser probing.Typical experimental results obtained in gas-puff and wire-array experiments on 1~3 MA facilities are also presented,including radiation power,zipper velocity,imploding velocity,convergence ratio,etc.
